题目-2：TAPs: An Architecture and Protocols for a High-Performance Multi-hop Wireless Infrastructure

时间段: 10：00-11：30

Abstract:

While high-speed wireless access is easy to achieve in an enterprise network via low-cost IEEE 802.11 (WiFi) access points, wireless technology in public spaces is in its infancy. ``Hot spots'' provide high-speed wireless access, but do so in very few isolated ``islands'' at immense costs. Likewise, while fixed wireless and 3G can provide ubiquitous coverage and 3G can support mobility, throughputs can often be two orders of magnitude slower than WiFi. In the following talk, I will make the case for the requirement of a fundamental new architecture based on beamforming antennas deployed on fixed, Transit Access Points (TAPs) that form a multi-hopping wireless backbone with a limited number of wired ingress/egress points. Moreover, I will describe a number of research issues including: physical layer design challenges, opportunistic and coordinated resource management, and challenges in achieving fairness.

Patrick Frantz is currently the Executive & Technical Director for Rice University's Center for Multimedia Communication, an institution devoted to next-generation wireless communications research. He received an M.E.E. degree from Rice University in 1997, returning to Rice in 2000 after spending some time working in the computer and biotechnology industries. He teaches several classes in high-speed hardware and embedded systems design, and has been involved with several wireless prototyping projects for experimental research, including one project that was a worldwide finalist in the 2000 Texas Instruments DSP and Analog Challenge. Patrick is also involved in developing international study programs for engineering students.
